Oh Lou, that sounds so uncomfortable and you have to take care of yourself. I know I always worked up until my due dates but I had a sit down office job when I was pregnant for my children. You do NOT have a sit down job! I agree that you should talk to your clients today and start making arrangements so you can take care of yourself. If you run into problems you will never forgive yourself and labour is not a joke. You can't be exhausted when it hits, it's too much work to bring a baby into the world. Take care of YOU! This time it's going to be ok to be a little bit selfish!
